Abstract

A method and system for initial and ongoing calibration of the absolute zero throttle plate reference position used in an electronic throttle control system. The method compensates for shifts in the absolute zero throttle plate reference position that occur as a result of ageing, wear, and thermal expansion/contraction by monitoring the torque output from a position controller when the throttle is commanded to be at the zero position, and correcting absolute zero position information until the torque required to maintain the absolute zero position is within a window extending between zero and that torque required to overcome a spring pre-load.
